Each shape represents where the people living in a state were born. Within a state, larger shapes mean a group makes up a larger share of the population.

On Thursday, we published a series of interactive charts showing how Americans have moved between states since 1900. The charts show striking patterns for many states: You can trace the rise of migrant and immigrant populations all along the Southwest, particularly in Texas and Arizona; the influx of New Yorkers and other Northeasterners into Florida starting in the 1970s; and the growth in the Southern share of the Illinois population during the Great Migration.
